An in situ infrared reflectance spectroscopic study of 1,2-propanediol electrocatalytic oxidation on platinum and gold
Bibliographic record
Abstract
L'etude in situ de l'oxydation electrocatalytique du 1,2-propanediol sur des electrodes de platine et d'or en milieu aqueux acide ou basique a ete realisee par spectroscopie infrarouge de reflexion. L'objectif de cette etude est l'identification des especes adsorbees et des produits de la reaction. Les spectres IR montrent plusieurs bandes d'absorption notamment deux bandes attribuables au monoxyde de carbone CO adsorbe et au dioxyde de carbone CO 2 . La bande autour de 1720 cm -1 est attribuee a la liaison carbonyle (C=O) d'un aldehyde ou/et d'un acide. A partir des resultats de la spectroscopie infrarouge et des electrolyses prolongees, nous avons propose un mecanisme reactionnel pour l'oxydation electrocatalytique du 1,2-propanediol.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
